Do velvet ants live in Indiana?

I would say yes. July 3 2012 I spotted a large red ant that looked different than any of the large red ants around here. I was planting some sprouted pumpkin seeds in the field. I pressed a small twig down upon the ant & there came its stinger trying to sting its way free. I was surprised to see what I had discovered since I have never seen a fire ant here in central Indian in the past 30 years living here. Even as a kid when I would play in the field with toy cars & tractors I never spotted ant like this one. So yes, fireants are here in central Indiana. I'm not sure how many but if there is one, there has to be a nest somewhere close by.
